Characteristics

Characteristics are in essence a segment with a static definition, meant to represent factual information about a user with the sole purpose of enhancing audience segmentation capabilities. For instance, the “Has Email” characteristic is comprised of all profiles that have some value for email. This can be viewed as an aggregate, how many users are a member of “Has Email,” or on the individual profile level.

It is best to think of characteristics as a high-level analytics metric as well as a set of predefined building blocks for your custom segments.
